The raw material of color.

Organic pigments offer greater brightness and tinting strength at lower dosages. Inorganic pigments provide higher opacity and greater heat and light resistance. The selection depends on the resin, the processing temperature and the end use, and many formulations combine both.

It is the resistance of the color to fading under light exposure. It is rated on the blue wool scale from 1 to 8, where 8 corresponds to the highest performance. For outdoor parts, high lightfastness pigments should be specified and confirmed on the technical data sheet.

It is the movement of the pigment within the part or toward its surface, where it can transfer to materials in contact. It is associated with overdosing, processing conditions outside the recommended range and additives competing at the surface. It is prevented by selecting pigments with migration resistance validated for that resin and that processing temperature.

Powder pigment offers full formulation control and a lower cost per kilogram, and requires dispersion equipment in house. Masterbatch arrives predispersed, doses cleanly and reproduces the shade with less batch to batch variation. For continuous color production, masterbatch is the more stable option.

Only those that meet the applicable reference, usually FDA for the intended use. In the Delta stock line catalog each masterbatch states whether it is recommended for food contact or not. It is best to declare the end use from the quote stage.

Through the website form, by WhatsApp or by phone. Send the shade reference, the system where it will be used (resin, water based, solvent based or ink), the process and the estimated volume. You can attach a photo of the part or the technical data sheet. With that we propose the pigment and confirm availability. Every request is reviewed within 24 business hours.
